FAQ’s

Absolutely. Residential plumbing rough-in is only part of the job; plumbers also perform fixture installation for new homes once walls, tile, and cabinetry are in place. Christianson Air Conditioning and Plumbing installs tubs, showers, toilets, bathroom and kitchen sinks, faucets, laundry hookups, hose bibbs, and specialty fixtures as part of our turnkey plumbing approach in San Antonio, TX.

By having the same team handle both rough-in and finish work, you gain consistency, fewer miscommunications, and fixtures that are installed exactly as the underlying plumbing system was designed. This is true for both new builds and remodeling and new construction plumbing projects throughout Greater San Antonio.

Reputable plumbers typically provide warranties on both labor and, when they supply them, many of the fixtures and equipment installed. Christianson Air Conditioning and Plumbing offers warranties on new construction plumbing work in San Antonio, TX, including workmanship on residential plumbing rough-in, drainage system installation, and fixture and water heater installations. Specific warranty terms can vary based on products and project details.

We stand behind our work with licensed plumbers, plumbing code compliance, and clear documentation at the end of each project. After move‑in, many homeowners in Greater San Antonio choose to enroll in the Christianson Annual Maintenance Program to keep their new systems inspected and maintained, helping preserve both performance and warranty coverage over the long term.

In San Antonio, TX, we typically check your home’s water pressure and PRV during scheduled visits as part of our Christianson Annual Maintenance Program (CAMP), rather than as a separate PRV‑only service. For most homes in Bexar County, an annual CAMP visit provides a good balance, especially in areas with higher municipal pressure or hard water. These routine whole‑home maintenance visits help us catch subtle changes in pressure before they turn into high water pressure plumbing problems, leaks, or valve failures, without you needing to remember a separate PRV inspection.

Yes. Licensed plumbers in Greater San Antonio can perform both PRV repair and PRV replacement, depending on the situation. If your valve is relatively new and the issue is limited, such as a minor leak, debris interference, or simple water pressure adjustment, repair is often practical. In older homes in areas like Alamo Heights in Bexar County, or in valves showing significant wear, corrosion, or chronic performance issues, replacement is usually the more reliable choice. At Christianson Air Conditioning and Plumbing, our plumbers serving San Antonio, TX, will inspect your valve, explain what they find, and recommend repair or replacement based on safety, cost, and long‑term performance.

In many parts of San Antonio, TX, and broader Bexar County, building codes and local standards require a water pressure regulator valve when incoming pressure exceeds a specified limit (often around 80 psi). Requirements can vary by jurisdiction and utility, but for most modern residential construction in Stone Oak and surrounding San Antonio communities, as well as Greater San Antonio as a whole, a PRV is either required or strongly recommended to protect your plumbing system and appliances. Christianson Air Conditioning and Plumbing stays current with local codes and will ensure that any pressure-reducing valve installation or PRV replacement we perform meets San Antonio and Bexar County requirements.

Plumbers in San Antonio, TX, commonly install several types of filtration systems, including whole‑home water filtration for entire‑house protection, under‑sink drinking water filters, and reverse osmosis systems for high‑purity drinking water. At Christianson Air Conditioning and Plumbing, we focus on whole‑house filtration tailored to your concerns and local water conditions, along with point‑of‑use solutions where extra filtration is desired.

We also provide whole-home water filtration system service, whole-home water filtration system replacement, and whole-house water filtration system replacement across Greater San Antonio and Bexar County, so your system can be maintained and upgraded as needs and conditions change.

Yes. Properly chosen filtration systems can significantly improve drinking water taste and odor in San Antonio, TX. Whole-home and point-of-use filters can reduce chlorine, certain chemicals, and sediment that often cause unpleasant flavors and smells. When combined with a reverse osmosis filter at a kitchen sink or refrigerator line, many homeowners in South & Central Texas notice a major difference in the clarity and taste of their drinking water.

Christianson Air Conditioning and Plumbing starts with water testing to identify what is affecting your water’s flavor, then recommends filtration configurations—such as carbon filters, sediment stages, and RO systems—designed to address those specific issues.

In most San Antonio, TX, homes, installing a standard whole-home or whole-house water filtration system can often be completed in a single day, assuming easy access to the main water line and adequate space near the entry point. More complex installations—such as combining filtration with water softeners, adding multiple stages, or dealing with tight or unusual plumbing layouts—may take longer.

When Christianson Air Conditioning and Plumbing evaluates your home in Greater San Antonio, we will outline the expected timeline for your whole home water filtration system installation or whole house water filtration system installation. Our team works efficiently to minimize downtime, test thoroughly, and leave your plumbing neat and ready for everyday use.

In most cases, “salt-based” water softeners use ion exchange to remove hardness minerals—calcium and magnesium—from the water and replace them with sodium or potassium ions. This truly softens the water and significantly reduces scale inside pipes and appliances. Salt‑free systems, by contrast, usually condition or alter the minerals so they are less likely to stick, but they do not remove hardness in the same way.

For many homes in San Antonio, TX, and across South & Central Texas, a traditional salt-based whole-home water softener installation provides the most effective protection against scale. Some households, however, may choose salt‑free conditioners for specific reasons. During an on-site evaluation in Greater San Antonio, Christianson Air Conditioning and Plumbing can review your water quality, goals, and plumbing layout to recommend the most appropriate approach.

Yes. Licensed plumbers are typically the right professionals to handle whole-home water softener installation, since these systems tie directly into your main water supply and require proper drainage and bypass setup. In San Antonio, TX, Christianson Air Conditioning and Plumbing provides turn-key installation, including plumbing connections, control setup, and post-installation testing.

We also offer whole-home water softener service, repair, replacement, and ongoing service throughout Bexar County and Greater San Antonio, so you have a single, trusted contractor for the life of your system.

Most water softeners benefit from at least an annual checkup, though some high-use systems or those on very hard water may need attention more frequently. In San Antonio, TX, where hardness levels can be high, yearly whole-house water softener service is a good baseline. This visit typically includes inspecting settings and components, checking brine tanks, cleaning internal parts as needed, and confirming that the system is regenerating properly.

Christianson Air Conditioning and Plumbing can tailor a maintenance schedule for your specific equipment and water conditions in Greater San Antonio and South & Central Texas. Many homeowners choose to include whole-home water softener service within our Christianson Annual Maintenance Program, so softener care is handled alongside other routine plumbing and HVAC visits.

In many parts of Texas, including San Antonio, TX, the most common water concerns are hard water minerals (calcium and magnesium), chlorine used for disinfection, sediment, and, in some areas, elevated total dissolved solids (TDS). These factors can cause scale on fixtures and appliances, dry skin, cloudy water, and noticeable taste or odor. More specialized testing can also reveal localized issues such as iron, manganese, or other substances, depending on the source and plumbing materials.

At Christianson Air Conditioning and Plumbing, we do not offer comprehensive water testing or formal water quality reports. We perform simple in‑home hardness tests as part of our water softener sales and installations. For broader contaminant testing, we recommend working with your local water utility or a certified independent water testing laboratory.

A water softener is designed primarily to reduce hardness minerals—calcium and magnesium—that cause scale and interfere with soap performance. It typically uses ion‑exchange media and a brine solution to remove these minerals from your water.

A water filtration system, by contrast, targets other concerns such as chlorine, sediment, certain chemicals, and sometimes specific metals or organics, depending on the filter type. In San Antonio, TX, and South & Central Texas, many homes benefit from both: a softener to protect plumbing and appliances from hardness, and a carbon filter to improve taste and odor. At Christianson Air Conditioning and Plumbing, we focus on hardness testing when selling or installing water softeners and on the performance of the softener and its included carbon filter. Homeowners who want more detailed contaminant analysis can also review information from their local water provider or work with a certified water testing lab.

For most homes on municipal water in San Antonio, TX, it’s a good idea to review water information from your local utility regularly and consider additional testing if you notice changes in taste, odor, staining, or water hardness. Homes with private wells, those that have experienced plumbing changes, or households with specific health concerns may benefit from more frequent or more detailed testing through a certified independent laboratory.

Christianson Air Conditioning and Plumbing does not provide full water quality testing panels or formal reports. Instead, we perform basic hardness tests when quoting or installing water softeners, and we can re‑check hardness during Christianson Annual Maintenance Program (CAMP) visits to confirm that your softener is working as intended. For broader contaminant testing, we recommend working directly with a certified lab or your water provider.

Yes. Slab leaks can significantly increase water bills in San Antonio, TX, because they are often on pressurized supply lines that run continuously. Even a relatively small leak under the slab can waste hundreds or thousands of gallons per month, driving up your bill without any obvious dripping faucet or running toilet to blame.

Homeowners across Greater San Antonio and Bexar County often first suspect a slab leak when they see a sharp, unexplained rise in water costs combined with subtle signs like warm floors or faint water sounds. Christianson Air Conditioning and Plumbing can perform targeted testing to confirm whether an under-slab leak is contributing to higher usage and then recommend appropriate slab leak repair.

The cost of slab leak repair in San Antonio, TX, varies widely based on factors like the leak’s location, the difficulty of accessing the pipe, whether direct repair or rerouting is chosen, the extent of concrete and flooring that must be removed and replaced, and whether multiple leaks or other piping issues are discovered. A simple, easily accessed repair will cost less than a complex reroute through finished walls or ceilings.

Because every home and leak is different, Christianson Air Conditioning and Plumbing provides pricing after assessing your specific situation in Greater San Antonio. While we offer free estimates for plumbing and HVAC new construction, remodel, and retrofit projects, general service slab leak repair and foundation leak repair are quoted per job, with straightforward, upfront pricing and financing available on qualifying projects.

In San Antonio homes, common signs of a slab leak include warm or damp spots on floors, unexplained increases in water bills, the sound of water running when all fixtures are off, cracks in walls or flooring that appear or worsen, musty odors near baseboards, and areas of standing water or persistent moisture around the perimeter of the foundation. In some cases, homeowners in Bexar County also notice low hot-water pressure or water heaters cycling more often than expected.

If you live in Greater San Antonio and notice one or more of these symptoms, it is wise to call a professional for slab leak detection. Christianson Air Conditioning and Plumbing can perform non-invasive tests and inspections to confirm whether a slab or foundation leak is present and then outline repair options that balance cost, disruption, and long-term reliability.

Backflow testing costs in San Antonio, TX, depend on how many devices need to be tested, the type and size of each assembly, and how accessible they are on your property. A single residential irrigation backflow test in Bexar County generally costs less than testing multiple commercial devices spread across a large site.

Christianson Air Conditioning and Plumbing provides straightforward pricing after confirming the number and type of backflow prevention assemblies at your home or business in Greater San Antonio. While we do not offer free estimates for general backflow service, many standard testing visits can be priced ahead of time, so you know the expected cost before scheduling.

Yes. Backflow issues can allow contaminated water—such as irrigation water, chemicals, or wastewater—to flow backward into clean water lines. In San Antonio, TX, this can occur if pressure changes or siphoning events happen and backflow prevention devices are missing, improperly installed, or not working correctly.

Proper backflow prevention and regular testing are critical for protecting drinking water in Bexar County and South & Central Texas. Christianson Air Conditioning and Plumbing’s certified backflow contractor team ensures devices are functioning as intended, reducing the risk of contamination in both your home and the public water system.

Qualified plumbers and backflow contractors in Greater San Antonio should provide documentation after completing backflow testing. At Christianson Air Conditioning and Plumbing, every backflow certification visit in San Antonio, TX, includes test results and any required forms for your records and, when necessary, for submission to your water provider or local authority.

Our technicians record device details, test readings, and any repairs performed, then issue appropriate certification so you can demonstrate compliance. We also track renewal dates and can remind you when it is time for your next annual backflow service in Bexar County.

Yes. Plumbers in San Antonio, TX, routinely repair running and leaking toilets, whether the issue is inside the tank, at the base, or in the supply line. At Christianson Air Conditioning and Plumbing, we handle everything from worn flappers and faulty fill valves to loose tank bolts, leaking shutoffs, and failing wax rings.

In Greater San Antonio and Bexar County, prompt toilet repair is important to prevent water waste, higher utility bills, and damage to flooring or subflooring. If your toilet runs constantly, cycles on and off by itself, or leaves water around the base, it is time to schedule service.

Coverage depends on your specific policy and what caused the damage. Many home insurance policies in San Antonio, TX, do not cover the cost of basic clogged toilet repair itself, but may cover resulting water damage if the clog leads to an overflow that damages floors, walls, or ceilings, provided the event is sudden and accidental. Long-term, neglected leaks are less likely to be covered.

If a severe clog or backup in Greater San Antonio has caused visible damage, you should contact your insurance company to review your policy details. Christianson Air Conditioning and Plumbing can document the cause, provide invoices, and help explain what repairs were necessary, which may assist in the claims process.

The cost of clogged toilet repair in San Antonio, TX, varies depending on factors such as the severity of the blockage, whether it is confined to the toilet or part of a deeper sewer issue, how accessible the toilet and cleanouts are, and whether additional repairs (like replacing internal parts or seals) are needed. Simple clogs that respond quickly to professional tools are typically less expensive than jobs that reveal larger drain or sewer problems.

Christianson Air Conditioning and Plumbing provides straightforward pricing after assessing your specific situation in Bexar County. While we do not offer free estimates for general service work, many standard clogged toilet repair and basic toilet installation or toilet replacement jobs can be quoted before an on-site visit, so you have clear expectations about costs.

Bathroom remodeling costs in San Antonio, TX, vary widely based on the size of the space, the quality of fixtures and finishes, whether you are changing the layout, and how much plumbing work is involved. Simple updates, like bathroom faucet replacement, bathroom sink replacement, and shower head replacement, typically cost far less than full tub replacement, shower replacement, and reconfiguring drains and water lines.

Christianson Air Conditioning and Plumbing provides detailed pricing after reviewing your specific project in Greater San Antonio. While we offer free estimates for plumbing and HVAC new construction, remodel, and retrofit work, general repair and small service items are quoted per job with straightforward, upfront pricing.

Many bathroom remodeling and bathroom renovation projects in San Antonio, TX do require permits, especially when they involve moving plumbing, adding new fixtures, altering structural elements, or changing electrical systems. Christianson Air Conditioning and Plumbing follows all applicable San Antonio and Bexar County codes and permitting requirements to ensure work is safe, legal, and properly inspected. If your project in San Antonio or surrounding areas includes major tub installation, shower replacement, toilet installation, or rerouting of water or drain lines, our team can help you determine which permits are needed and coordinate with your general contractor to handle the process correctly.
If your project in the Austin or Bexar County region includes major tub installation, shower replacement, toilet installation, or rerouting of water or drain lines, our team can help you determine which permits are needed and coordinate with your general contractor to handle the process correctly.

Yes. Reputable plumbers in South & Central Texas typically offer warranties on labor and, in many cases, on fixtures they supply. Christianson Air Conditioning and Plumbing provides warranties on bathroom faucet installation, bathtub installation, toilet replacement, and related plumbing work for remodels and renovations in San Antonio, TX, and Greater San Antonio. Warranty terms may vary depending on the type of fixture and the scope of work.

Our Christianson Annual Maintenance Program can further support your new bathroom by including periodic inspections and service, helping ensure that tub replacement, shower head replacement, bathroom faucet repair, and other upgrades continue to perform well for years after the remodel is complete.

In many cases, garbage disposals in San Antonio, TX, can be repaired if the issue is a simple jam, tripped reset button, loose connection, or minor leak at the mounting assembly. Our plumbers will first check for safe, cost-effective garbage disposal repair options. However, if the motor is burned out, the housing is cracked, or the unit is very old and unreliable, garbage disposal replacement is often the better long-term solution.

Christianson Air Conditioning and Plumbing provides honest recommendations for homeowners across Bexar County and Greater San Antonio, explaining when a quick fix makes sense and when a new garbage disposal will offer quieter, more efficient performance.

Yes. Even small, slow leaks under a kitchen sink can cause significant damage over time. In homes around San Antonio, TX, we often see cabinet bottoms warped, swollen, or covered in mold due to long-term moisture from leaking drain connections, loose basket strainers, failing garbage disposals, or deteriorated supply lines. Left unaddressed, these leaks can also damage adjacent flooring and promote mildew odors.

Prompt kitchen sink repair or fixture repair is essential to prevent this kind of damage. Christianson Air Conditioning and Plumbing can assess the condition of your under-sink plumbing, perform needed fixture replacement or pipe repairs, and help you prevent future leaks in Greater San Antonio kitchens.

Yes. Many plumbers in South & Central Texas, including Christianson Air Conditioning and Plumbing, install a variety of water filtration systems in kitchens—ranging from under-sink filters and dedicated drinking water faucets to refrigerator line filters and whole-home filtration that benefits every tap. In San Antonio, TX, where water quality and taste can be a concern, properly installed filtration makes a noticeable difference.

During a kitchen plumbing installation or remodel, we can integrate filtration into your design, coordinate with kitchen faucet installation (for filtered faucets or separate taps), and ensure that lines are routed cleanly and safely. Our team serves homeowners throughout Bexar County and Greater San Antonio with customized solutions that fit your space, budget, and water quality goals.

The length of time sewer line replacement takes in San Antonio, TX, depends on factors like the length and depth of the line, soil conditions, how many utilities cross the route, and whether concrete, trees, or other obstacles are in the way. Many straightforward residential replacements in Bexar County can be completed in one to several days, while more complex projects may require additional time for excavation, inspection, and restoration.

Christianson Air Conditioning and Plumbing will provide a projected schedule after evaluating your specific property and sewer layout. We work efficiently to minimize disruption while ensuring your new sewer line is installed safely and correctly.

Yes. In most cases, permits are required for sewer line replacement in San Antonio, TX. Local codes and regulations are in place to ensure that sewer work is performed safely, meets health standards, and protects the public sewer system. As a licensed sewer contractor, Christianson Air Conditioning and Plumbing obtains the necessary permits, coordinates inspections, and ensures your sewer pipe replacement or sewer line replacement complies with all applicable codes in Greater San Antonio and Bexar County.

Handling permits through our team saves you time and helps prevent delays or complications with city inspectors.

Yes. In many situations, plumbers can repair or replace only the damaged portion of a sewer line instead of replacing the entire run. Partial sewer line repair or sewer pipe repair is often a good option when a sewer camera inspection shows that most of the line is in good condition and problems are limited to a small area, such as a single crack, offset joint, or root intrusion point.

Christianson Air Conditioning and Plumbing evaluates your sewer line in San Antonio, TX, and Greater San Antonio to determine whether spot repairs, sectional sewer pipe replacement, or full sewer line installation is the best approach. We will explain the pros and cons of each option, including cost and expected lifespan, so you can choose the solution that fits your home and budget.

In most San Antonio, TX, homes, a typical sewer video inspection takes between 45 minutes and 2 hours, depending on access points, pipe length, and how many problem areas we find. Simple inspections with clear, accessible cleanouts are usually quicker, while older homes in Bexar County with multiple bends, limited access, or heavy buildup may take longer to navigate and document.

Christianson Air Conditioning and Plumbing schedules enough time to perform a thorough sewer drain line inspection, review the video with you, and explain repair or maintenance options. If your situation is complex or tied to a larger project, we will let you know up front what to expect.

Yes. One of the main advantages of sewer camera inspection is that it is minimally invasive. In most Greater San Antonio homes, we access the sewer system through existing cleanouts, roof vents, or other service openings—so there is usually no need to dig up your yard or break concrete just to see what is happening inside the pipes.

While repairs may still require excavation or other work depending on what we find, the sewer video inspection itself is focused on information gathering with as little disruption as possible. Christianson Air Conditioning and Plumbing uses this non-destructive approach to give homeowners across South & Central Texas a clear picture of their sewer’s condition before any repair decisions are made.

Requirements depend on local regulations and the terms of the sale, but sewer inspections are not universally mandated for every home sale in San Antonio, TX. However, many buyers, sellers, and real estate professionals in Greater San Antonio and Bexar County strongly recommend a sewer video inspection as part of due diligence—especially for older homes or properties with large trees, previous plumbing issues, or unknown sewer histories.

A sewer drain line inspection from Christianson Air Conditioning and Plumbing can reveal hidden problems before closing, allowing for repairs, price adjustments, or warranty negotiations. Even when not required, this relatively small investment can prevent major surprises and expenses after you move in.

The cost of professional drain cleaning in San Antonio, TX, depends on factors such as the type and location of the clog, whether it is a single fixture or a main line, how accessible the cleanouts are, and whether additional services (like camera inspections or repairs) are needed. Clearing a simple clogged drain near a sink or tub is typically less involved than removing tree roots or heavy buildup in a long sewer run.

Christianson Air Conditioning and Plumbing provides pricing after assessing your specific situation in Bexar County and Greater San Antonio. While we do not offer free estimates for general service, many standard drain cleaning and clogged drain repair jobs can be quoted before an on-site visit, so you have a clear idea of expected costs.

Yes. Many over-the-counter chemical drain cleaners are harsh and can damage certain types of piping, weaken joints, and deteriorate rubber or plastic components over time. In older homes around San Antonio, TX—especially those with aging metal or cast iron pipes—repeated use of strong chemicals can accelerate corrosion and make future clogs and leaks more likely.

In Bexar County and South & Central Texas, we generally recommend avoiding prolonged use of aggressive chemical products. Instead, professional drain cleaning with mechanical tools, rooter service, or safe treatments is usually more effective and far gentler on your plumbing system. Our technicians can suggest the best options for your drains and pipe materials.

Many professional plumbers in Greater San Antonio do offer camera inspections for drains and sewer lines. Christianson Air Conditioning and Plumbing uses Sewer Video Inspection to look inside main lines and some branch lines when needed, especially for recurring blockages, suspected breaks, root intrusion, or when buying or remodeling a home in San Antonio, TX.

A camera inspection lets our team see exactly what is causing the problem—whether it is roots, collapsed pipe, offset joints, or heavy scale—and then recommend the right fix, from targeted clogged drain repair to more substantial sewer work. This helps you avoid guesswork and choose the most cost-effective long-term solution for your home.

In San Antonio, TX, water line leaks are often caused by a combination of soil movement, aging materials, corrosion, high water pressure, and tree root intrusion. Certain older piping materials used in Bexar County are more prone to rust and thinning over time, which can lead to pinhole leaks or sudden breaks. Shifting clay soils and construction around the property can also stress and crack pipes, leading to the need for main water line repair or even full water main line replacement.

Christianson Air Conditioning and Plumbing evaluates both visible conditions and underground factors when diagnosing leaks in Greater San Antonio, recommending either targeted water main line repair or more comprehensive replacement based on what we find.

The cost of water line repair in San Antonio, TX, depends on several factors: the location and depth of the leak, how accessible the line is, the length of pipe that needs to be repaired, and whether other utilities or structures are nearby. A small, shallow repair close to the meter generally costs less than a deeper leak under a driveway or mature landscaping that requires more excavation and restoration.

Because every property is different, Christianson Air Conditioning and Plumbing provides pricing after assessing your specific situation in Bexar County. While we do not offer free estimates for general service work, many common main water line repair and water main line repair jobs can be quoted to homeowners before an on-site visit, so you have a clear idea of expected costs.

You may need main water line replacement or water main line replacement if you experience recurring leaks along the same line, have very old or corroded piping, notice consistent yard saturation, or see a pattern of high water bills and pressure problems even after repairs. Homes in Greater San Antonio with older galvanized or failing plastic lines are especially likely to benefit from full line replacement instead of piecemeal fixes.

A qualified plumber in San Antonio, TX, can inspect accessible sections, review your repair history, evaluate water quality and pressure, and help you decide whether continued water main line service and repairs are wise—or if a new main water line installation will provide better long-term reliability and value. Christianson Air Conditioning and Plumbing walks you through both options, with straightforward pricing and financing available for qualifying replacement projects.

The cost of gas line installation in San Antonio, TX, depends on several factors, including the length of the run, whether the line is indoors or underground, how many bends or obstacles must be navigated, the size of piping required for your natural gas load, and whether new shutoff valves or regulators are needed. Installing a short branch for a single appliance is usually less expensive than running a new main line across a property.

Because each home is different, Christianson Air Conditioning and Plumbing provides pricing after evaluating your specific situation in Bexar County and Greater San Antonio. For gas piping that is part of plumbing or HVAC new construction, remodels, or retrofit projects, we offer free estimates; general service gas line installation is quoted per job with transparent, upfront pricing.

Not all plumbers perform gas work, but reputable companies in San Antonio, TX, ensure that technicians handling gas lines are properly licensed and qualified. At Christianson Air Conditioning and Plumbing, our gas fitters and plumbing teams are licensed and insured, trained in current fuel gas codes, and experienced with both gas line repair and gas line installation.

We follow all local and national standards for natural gas piping, obtain necessary permits, and coordinate with inspectors to ensure your system is safe and compliant throughout Bexar County and the surrounding region.

Yes, many plumbers are trained to work on both natural gas and, where codes and regulations allow, propane systems. In South & Central Texas, Christianson Air Conditioning and Plumbing services a wide range of residential gas systems, including natural gas lines supplied by utilities and certain propane setups.

We handle gas line repair, gas line replacement, and gas appliance hook-up for many types of gas-fueled equipment. When you call from San Antonio, TX, or nearby communities, our office can confirm the type of gas service you have and schedule the appropriate technician to safely perform the work.

Most homes in San Antonio, TX, have a main shutoff valve either where the water line enters the house, in a utility room, or near the meter box outside. Turning this valve clockwise usually stops water to the entire home. Many fixtures also have individual shut-offs under sinks or behind toilets that can isolate specific areas.

If a burst water pipe occurs, shutting off the main as quickly as possible is often the best way to minimize damage. When you call Christianson Air Conditioning and Plumbing for burst pipe repair in Bexar County or Greater San Antonio, our team can help guide you by phone to locate and safely operate your shutoff valves until a plumber arrives.

Coverage depends on your specific policy and the circumstances, but many homeowners’ insurance policies in Greater San Antonio do cover sudden and accidental water damage from a burst pipe. Often, the cost to access and repair damaged walls and floors is included, while the actual burst pipe repair or replacement may or may not be fully covered.

We recommend contacting your insurance provider as soon as possible after a burst in San Antonio, TX, to understand your coverage. Christianson Air Conditioning and Plumbing can document what we find, provide invoices and descriptions of work performed, and coordinate timing with restoration companies so you can move through the claim process more easily.

Yes. In South & Central Texas, including the San Antonio, TX, area, burst pipes in or under slabs can contribute to foundation issues if they are not addressed quickly. A burst water pipe beneath your home can wash away soil, create voids, and introduce moisture that affects slab stability and nearby structural elements.

Prompt leak detection, repair, and—when necessary—pipe rerouting are essential to minimize these risks. If we suspect that a slab-related burst has impacted your foundation, Christianson Air Conditioning and Plumbing will advise you to consult with a qualified foundation specialist after we complete the plumbing repairs, helping you protect your home’s long-term structural health.

Many plumbers in Greater San Antonio do offer financing for tankless water heater installation, especially for full system upgrades or conversions from traditional tanks. Christianson Air Conditioning and Plumbing provides financing options on qualifying projects in San Antonio, TX, and surrounding communities, making it easier to invest in a high-efficiency on-demand water heater without paying everything up front.

During your estimate, we can review equipment choices, expected operating savings, and available payment options so you can choose the approach that best matches your household budget and long-term plans.

Yes. Tankless water heaters are well-suited to San Antonio’s climate, as the relatively mild winter temperatures and higher incoming water temperatures help improve performance and efficiency. In Bexar County and South & Central Texas, properly sized and installed gas tankless units can provide very reliable instant hot water for many years.

Reliability depends on correct sizing, quality installation, water quality management, and regular maintenance, including periodic tankless flush services. Christianson Air Conditioning and Plumbing designs systems with these factors in mind and offers maintenance plans to keep your equipment performing consistently over time.

Installation timelines vary based on whether you are replacing an existing tankless unit or converting from a traditional tank system. In many San Antonio, TX, homes, a straightforward replacement can often be completed in a single day once equipment and permits are ready. Conversions that require new gas lines, venting changes, or electrical upgrades may take longer.

When we evaluate your home in Greater San Antonio, we will outline the expected schedule for your tankless water heater installation, including any preparatory work required. Our team works to minimize downtime so you regain reliable hot water as quickly as possible.

In Texas, most traditional tank-style water heaters last 8–12 years, depending on the unit’s quality, installation, local water conditions, and whether it receives routine maintenance. In Greater San Antonio and Bexar County, hard water can shorten the life of tanks if they are never flushed or if anodes are not checked and replaced when needed.

Christianson Air Conditioning and Plumbing recommends regular inspections and maintenance to help extend the lifespan of your gas water heater or electric water heater. When your unit nears the end of its expected life, we can help you plan a timely water heater installation or replacement before a major leak or sudden failure occurs.

For many homes in San Antonio, TX, flushing a tank-style water heater once a year is a good starting point, but homes with very hard water or high hot water use may benefit from more frequent flushing. Regular flushing helps remove sediment that settles at the bottom of the tank, which can reduce efficiency, cause noise, and promote premature wear.

During service visits, our technicians can identify signs of sediment buildup and recommend an appropriate schedule for your home in Bexar County. Incorporating flushing into routine maintenance not only supports more efficient operation, it can also help protect internal components and delay the need for hot water tank repair or replacement.

Yes. Hard water—which is common throughout South & Central Texas—can significantly impact the performance and lifespan of a water heater. Mineral deposits from hard water can build up inside the tank, on heating elements, or around burner surfaces, forcing the system to work harder to heat the same amount of water and increasing the risk of early failure.

Christianson Air Conditioning and Plumbing frequently sees sediment-related issues in water heater repair calls around Greater San Antonio. To combat hard water, we may recommend regular flushing, temperature adjustments, and, in many cases, installing a Nugen Systems Water Softener or similar treatment solution. Combining water treatment with preventative maintenance and timely hot water tank repair helps protect your investment and keep your hot water system running smoothly.

Yes. Emergency plumbers in San Antonio, TX, regularly handle serious sewer backups where wastewater is coming up through toilets, tubs, or floor drains. In these situations, stopping the use of all fixtures and calling for help right away is critical to preventing additional contamination and damage.

Our plumbers at Christianson Air Conditioning and Plumbing do repair and replace water heaters when the situation is urgent. In San Antonio, TX, we often respond to leaking tanks, no-hot-water situations in homes with vulnerable occupants, and suspected gas or electrical hazards related to water heaters.

In some cases, we can perform immediate emergency plumbing repair to make the unit safe or restore function. If a full replacement is required, we stabilize the situation first, then return during regular hours for installation with straightforward pricing and available financing options on qualifying systems.

Most homes in San Antonio, TX, have a main shutoff valve located where the water line enters the house, in a utility room, or near the meter. Turning this valve clockwise usually stops water flow to the entire home. Many fixtures, such as toilets and sinks, also have individual shutoff valves on the supply lines beneath or behind them.

If you are facing a serious leak or backup and can safely reach the main or fixture shutoff, turning off water is one of the best ways to limit damage while you wait for an emergency plumber. When you call Christianson Air Conditioning and Plumbing for 24-hour plumbing repair in Greater San Antonio, our team can help guide you over the phone to the likely location of your shutoffs and explain how to operate them safely.

At Christianson Air Conditioning and Plumbing, we offer free estimates for plumbing and HVAC new construction projects, remodels, and retrofit work in San Antonio, TX, and the Greater San Antonio region. This includes planned projects where design and scope can be reviewed in advance.

For general plumbing repair and routine residential plumbing service, we do not provide free estimates. However, many common services—such as typical drain clearing, fixture replacements, or standard repairs—can be quoted to homeowners before an on-site visit so you have clear expectations about pricing before work begins.

Often, plunging the sink drain will dislodge the obstruction. If plunging does not work and the sink still doesn’t drain, you can remove the “trap” under the sink.

The trap is the U‑shaped section of pipe. Detach it by unscrewing both ends (place a bucket underneath to catch water). Once the trap is off, look for and remove any obstructions.
If you can’t find or reach the blockage—or are uncomfortable removing plumbing parts—call a plumbing expert. If you have one, you can also try using a plumber’s snake to clear the obstruction.

An aerator is a small device attached to the tip of a faucet. It breaks a single stream of water into many smaller streams, which helps reduce splashing and conserve water.

Small bits of sediment can clog the aerator and reduce water flow. If you notice a reduced flow from a faucet, unscrew the aerator, clean the screen or filter, and reattach it.

First, do not keep using a jammed disposal—it can damage the motor or electrical system. Turn off the power to the unit. Many disposals have an opening on the bottom where you can insert an Allen wrench and turn it to help free the jam. If that doesn’t work, or you’re unsure, contact a plumber.

• Tank‑style water heaters: The most common type in the U.S. They store hot water in an insulated tank, using a burner or electric element. Energy is consumed to keep water hot, even when you’re not using any.
• Tankless water heaters: These do not store water. They heat water on demand using a gas burner or electric element, so energy is used only when you need hot water.

It is normal for some water to remain at the bottom of a dishwasher at the end of a cycle to keep the heating element from overheating.

However, if the dishwasher does not empty at all, possible causes include a clogged drain line, a faulty motor, or an electronic issue. At that point, it is best to have a professional inspect the system.

Place a few drops of food coloring into the toilet tank and wait a few minutes without flushing. If the water in the bowl takes on the same color, water is leaking from the tank into the bowl. Even a slow leak can waste hundreds of gallons of water over time.

Vents are critical for any plumbing system to operate properly. They:

• Allow sewer gases to escape safely through vent pipes, usually through the roof
• Help maintain proper air pressure in the drains
• Reduce the chance of sewer gas odors entering the home or office

Without proper venting, drains can be slow, noisy, and smelly.

Always turn off the power to the disposal before working on or near it. A few ways to clean and freshen it include:

• Bleach solution: Mix about one tablespoon of bleach with a gallon of water and pour it down the drain into the disposal. Let it sit for a few minutes, then run cold water through the drain for 30–45 seconds.
• Citrus and ice: Place citrus rinds (like orange or lemon peels) and a few ice cubes into the disposal, then run it. The ice helps clean the grinding surfaces, and the citrus rinds add a fresh scent.

Shutoff valves are typically found under or beside each plumbing fixture. For example, the shutoff valves for a kitchen faucet are usually directly under the sink.
You should shut these valves off when replacing a fixture (like a faucet or toilet) or if there is a leak at that fixture. There is also typically a main shutoff for the home that stops water to the entire building.

If only the hot water appears dirty or brownish, common causes include:

• Rust entering the water lines due to certain chemicals or aging pipes
• Sediment from the water heater traveling into the hot water lines
• A defective water heater lining allowing rust to form and discolor the water

If discoloration persists, it’s a good idea to have your water heater and piping checked by a professional.

Evaporator coil replacement in a typical residential system usually takes several hours, often fitting within a single workday, assuming adequate access and no major complications. Factors such as attic or closet location, unit configuration, and the need for additional repairs (like drain pan replacement or line set modifications) can affect total time.

When we evaluate your system in San Antonio, TX, or elsewhere in South & Central Texas, Christianson Air Conditioning and Plumbing will provide a realistic timeline for evaporator coil replacement or evaporator coil installation, including recovery of refrigerant, installation steps, recharging, and final testing.

Evaporator coils are often covered under manufacturer parts warranties for a specified period—commonly 5–10 years—on new systems, provided the unit was registered and installed according to guidelines. Labor, however, is frequently a separate consideration and may or may not be included. Warranty coverage can also depend on consistent maintenance and the use of compatible components.

In San Antonio, TX, Christianson Air Conditioning and Plumbing helps homeowners in Greater San Antonio and Bexar County review their system documentation to determine whether evaporator coil repair or evaporator coil replacement may be partially covered by existing warranties. We also assist with proper installation and documentation on new systems to help protect your warranty coverage from the start.

Replace disposable filters at least once a month. If you have washable filters, clean them once a month. Dirty filters restrict airflow, which negatively impacts system performance and efficiency.

Electronic air cleaners can play a big part in whole‑home comfort and cleaner indoor air. There are a number of effective whole‑house filtration systems available. You can learn more by visiting our Air Conditioning page or speaking with a Christianson technician.

Yes. Programmable thermostats are generally more accurate and efficient than conventional thermostats. They automatically adjust temperature settings based on your schedule and needs, helping reduce energy use and improve comfort.

The easiest and most critical step is to clean or replace all filters once per month. In addition, avoid thermostat settings that cause the system to turn off and on frequently (short cycling), as that can reduce efficiency and shorten equipment life.

Air conditioning systems should have maintenance performed twice a year. The main benefits are:

• Keeping your system running at maximum efficiency
• Minimizing repair costs
• Detecting issues before they become major problems

No. Contrary to popular belief, closing air vents or doors to unused rooms can decrease your system’s airflow and efficiency. It disrupts designed airflow and causes your air conditioning system to work harder and less efficiently.

Before purchasing a replacement system, always make sure it is sized properly. A licensed air conditioning expert should perform a load analysis on your home to ensure proper sizing. Bigger is not always better—an oversized system can be inefficient and may raise your monthly utility bills.

There are too many variables to give an accurate price without a proper onsite evaluation. Factors include:

• Size of the home and layout
• Ceiling heights
• Existing ductwork and return air capacity
• Your comfort preferences and efficiency goals

An air conditioning expert should provide a free estimate for a replacement system after visiting your home or business. Be cautious of any quote given only over the phone.

As with cost, proper sizing requires an on-site evaluation. Considerations include:

• Size of the home
• Floor plan and ceiling heights
• Existing ductwork
• Return air capacity

Proper sizing is critical to efficiency, comfort, and equipment life, and should always be performed by a licensed air conditioning expert.

Not necessarily. A system with too much capacity may turn on and off frequently (short cycles), which can reduce efficiency and increase wear and tear. In many cases, an oversized air conditioner is actually less efficient and more expensive to operate than a right‑sized unit.

S.E.E.R. (Seasonal Energy Efficiency Ratio) measures how much cooling your system delivers per dollar spent on electricity. As a rule, the higher the S.E.E.R., the more efficient the system—and the more you can save on monthly utility bills, compared to lower‑rated equipment.

When it is cold outside, a heat pump will accumulate frost on the outdoor coil and exposed lines. To remove this frost, the unit enters a defrost mode. During defrost, the heat pump may blow cooler air inside and make unusual noises. Once the defrost cycle is complete, the system will return to its normal heating mode.

That depends on your comfort preferences. As air is heated, it naturally dries out, which can cause sinus irritation, static electricity, and dry skin. Adding a humidifier introduces moisture to the air and helps minimize or eliminate many issues caused by overly dry indoor air.

Yes. Refrigerant leaks are more common in older AC units, especially those that have experienced years of heavy use, corrosion, or previous freeze‑up events. In San Antonio, TX, systems exposed to high heat, dust, and long run times often develop small leaks in coils, line sets, or fittings as they age.

Homeowners throughout Greater San Antonio and South & Central Texas frequently call Christianson Air Conditioning and Plumbing for ac refrigerant leak repair on systems 10–15 years old or more. In many cases, we can repair leaks cost‑effectively; in others, we may recommend considering replacement when ongoing leaks and AC refrigerant replacement become uneconomical.

The time required for refrigerant leak repair in San Antonio, TX, depends on the complexity and location of the leak. Simple repairs, such as tightening a fitting or addressing a minor line leak, may be completed within a few hours, including evacuation and freon service or recharge. More complicated leaks—like those in evaporator or condenser coils, or those requiring line set replacement—can take longer and may span part or all of a workday.

Christianson Air Conditioning and Plumbing assesses each situation on-site in Greater San Antonio and Bexar County and provides an estimated timeline before work begins, so you know how long your system will be offline during ac refrigerant leak repair and ac refrigerant replacement.

In many San Antonio, TX, homes, a straightforward single‑zone ductless mini split installation can often be completed in a day, assuming electrical service and mounting locations are ready and access is reasonable.

The decision to repair or replace a heating system in San Antonio, TX, depends on age, condition, and repair history. If your furnace or heater is relatively new, has been well maintained, and the current issue is minor and affordable to fix, repair is often the best choice. However, if your system is 12–15 years old, requires frequent or costly repairs, or if a major component such as the heat exchanger or compressor has failed, replacement may be more economical and reliable in the long run.

Christianson Air Conditioning and Plumbing helps homeowners throughout Greater San Antonio and Bexar County weigh these factors. Our heating contractor and furnace contractor teams provide honest assessments, outlining repair vs. replacement costs and expected life span so you can make an informed decision.

Yes. Many HVAC companies in San Antonio, TX, including Christianson Air Conditioning and Plumbing, provide emergency heating repair for situations where loss of heat creates safety or health concerns.

Common signs your heating system may be failing in San Antonio, TX, include increasing repair frequency, uneven heating from room to room, unusual noises (such as banging, popping, or squealing), short cycling, persistent burner problems, and rising energy bills despite regular maintenance. Age is also a factor—systems past 12–15 years old in Greater San Antonio often show more frequent and serious issues.

If you notice these symptoms in Bexar County or surrounding South & Central Texas areas, it is wise to schedule an evaluation with an experienced HVAC Contractor. Christianson Air Conditioning and Plumbing can inspect your system, recommend appropriate heater service or furnace service, and let you know whether proactive replacement is worth considering before a complete breakdown occurs.

In San Antonio, TX, the cost of whole-home air filtration varies based on the type of system, your existing HVAC setup, and the level of filtration you choose. A basic upgraded media cabinet is generally less expensive than advanced multi‑stage systems that combine filtration and purification. Christianson Air Conditioning and Plumbing provides clear, upfront pricing for air filtration installation in Greater San Antonio and can discuss financing options and potential rebates from many municipal and utility providers for qualifying efficiency upgrades.

Most HVAC companies in Bexar County focus primarily on central, whole‑home solutions, though some may also advise on portable units.

In many Greater San Antonio homes, installation of a whole home air purifier or whole house air purifier can be completed in about half a day, assuming the existing ductwork and equipment are in good condition and easily accessible. More complex setups in older homes or tight spaces around San Antonio, TX, may take longer if duct modifications are needed. During your appointment, Christianson Air Conditioning and Plumbing’s technicians perform the air purifier installation, test the system thoroughly, and explain how to operate and maintain it as part of your ongoing air purifier service and air purifier repair plan.

In San Antonio, TX, most homes benefit from a professional duct inspection every two to three years, with more frequent checks if you notice airflow changes, unusual dust, or have completed major remodeling. Full cleaning is not always necessary on that schedule, but in many Greater San Antonio homes, a thorough cleaning every five to seven years can be helpful, especially if there are pets, smokers, or recent construction. During routine HVAC visits, Christianson Air Conditioning and Plumbing also performs basic visual checks of accessible ductwork to catch obvious problems early.

In Bexar County and the surrounding region, properly installed and maintained ductwork often lasts 20–25 years, sometimes longer for metal ducts kept in good condition. Flexible ducts may have a shorter practical lifespan due to heat exposure, physical damage, or material degradation in hot attics. If your ducts in South & Central Texas are approaching a couple of decades old and you are experiencing comfort or efficiency issues, it may be time to consider air duct replacement or partial ductwork replacement to bring performance back up to modern standards.

Yes. Many HVAC noise complaints in San Antonio, TX, are actually duct‑related rather than equipment failures.
